You can notice it with Chrome 7.0.517.44 and Konqueror 4.5.3. If you slowly resize the viewport width, then a tiny sliver of red will appear (intermittently) on the right side of the green square. This is only because of width: 50% which can apply to an odd number of available width of body (minus body horizontal margins) in which case a fraction of a pixel is dropped, truncated, rounded down. What I am trying to say is that due to rounding down of the p's width when the available width of its parent has an odd number, the green square horizontal position will be missing 1px. So this could happen to any tester if he/she does not have a maximized viewport. pattern-tr.png on the other hand will always be (perfectly) horizontally centered from its pixel 16. One other thing with that testcase is the gratuitious, unnecessary, unneeded double declaration of font-size in the testcase. There is no reason for div { ... font-size: 10px; } p { ... font-size: 2em; } in that testcase. regards, Gérard -- Contributions to the CSS 2.1 test suite: http://www.gtalbot.org/BrowserBugsSection/css21testsuite/ CSS 2.1 test suite (RC3; October 27th 2010): http://test.csswg.org/suites/css2.1/20101027/html4/toc.html CSS 2.1 test suite contributors: http://test.csswg.org/source/contributors/
